Hello all, Hope everyone has been enjoying the holiday so far. I have a question about transcript and course numbers. I am doing my BA at a a top 10 private school in the US. While at other institutions, undergraduate courses are numbered 100-400 and graduate courses 500 and above (to the best of my understanding), my university up until this Fall (2012) number undergraduate courses from 1 to 199, and graduate courses 200 to 399. They switched to the new system recently. Thus someone who doesn't read the small denotation on the transcript about the old vs. new numbering system (a very small sentence, I might add) might be confused and think that I only took introductory courses up until Spring 2012, and then suddenly skipped to 300 and 400 level courses for this semester. My question is, is the concern above valid? Should I personally contact the adcoms at every school I'm applying to just to tell them about this (some applications don't have room/space for me to explain)? My school is a big research university, very well-known, and probably have sent thousands to grad school. Thanks!
